Amechania as an existential a priori and a prerequisite for human life experience

Based on existential a priori structures, the research demonstrates the possibility of particular sciences to hold a dialogue with the philosophical ideas that leads to their further evolution and gives the philosophical ideas the opportunity to comprehend the phenomena of interest to it. The research focuses on the specific features of a philosophical approach to interpreting the term ‘existential a priori’ developed by L. Binswanger. In the author’s opinion, amechania can be regarded as an a priori structure that constitutes the human life experience. The notion of amechania as treated by M.K. Mamardashvili, A.V. Akhutin, V.V. Bibikhin is analysed as well. The relevance of the study is postulated by the ongoing discussions about the relationship between philosophy and particular sciences both in the historical and modern terms.
